CVE-2026-41049: CWE-303 Incorrect implementation of authentication algorithm in presire qSnapper
Incorrect caching of authentication between different users of the qSnapper dbus service before version 1.3.3 allowed any local attacker to use dbus functions after a privileged users has authenticated for them.
AI Analysis
Technical Summary
The vulnerability CVE-2026-41049 in presire qSnapper is due to an incorrect implementation of the authentication algorithm (CWE-303). Specifically, the qSnapper dbus service improperly caches authentication data between different users, enabling a local attacker to leverage the authenticated state of a privileged user to invoke dbus functions without proper authorization. This issue affects versions =1.2.1 and >=1.2.1 <1.3.3. The CVSS 4.0 base score is 8.4, reflecting high severity with local attack vector, low attack complexity, no user interaction, and high impact on confidentiality and integrity. No official patch or remediation level has been confirmed yet.
Potential Impact
A local attacker can exploit this vulnerability to perform dbus operations with the privileges of a previously authenticated privileged user. This can lead to unauthorized access and potential manipulation of system functions accessible via dbus, compromising system confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only to reduce risk. Monitor vendor channels for updates regarding patches or official mitigations.
